Overview
Anti-pan ASIC (extracellular) Antibody is an antibody targeting Acid-sensing ion channel, Acid-sensing (proton-gated) ion channel, ACCN, ACCN2, ACCN3, ACCN4 Polyclonal raised in Rabbit (Unconjugated). This antibody is commonly used in IC, IF, IFC, IHC, LCI, WB to detect, localize, or compare expression of the target across samples.
Key elements and design rationale
- Target: Acid-sensing ion channel, Acid-sensing (proton-gated) ion channel, ACCN, ACCN2, ACCN3, ACCN4 (also reported as Acid-sensing ion channel, Acid-sensing (proton-gated) ion channel, ACCN, ACCN2, ACCN3, ACCN4).
- Immunogen/epitope region: Extracellular loop.
- Homology note: ASIC1: Mouse, rat, human - identicalASIC2: Mouse, rat, human - 14/15 amino acid residues identicalASIC3: Mouse, rat, human - 12/15 amino acid residues identicalASIC4: Mouse, rat - 12/15 amino acid residues identical; human - 11/15 amino acid residues identical (informative for cross-species interpretation).
- Species reactivity (as provided): Human, Rat, Mouse.
- Lot quality control (as provided): Western blot analysis.
- Peptide confirmation: Confirmed by amino acid analysis and mass spectrometry.
- Blocking peptide: Available for antigen preadsorption control where appropriate.
- Conjugate/format: Unconjugated (may affect detection channel and background).
These attributes help researchers interpret whether signal reflects the intended target in a given assay and sample context.
Biological background
ASIC channels belong to the ENaC/Degenerin superfamily and are proton-gated ion channels which are not voltage-dependent. Six different genes encode the different ASIC subunits and splice variants: ASIC1a, ASIC1b, ASIC2a, ASIC2b, ASIC3 and ASIC4.ASIC channels sense protons and interact with proteins (namely proteases) and other ions such as Zn2+ and Ca2+ through their extracellular domains. The extracellular loop of ASIC1a undergoes cleavage by extracellular trypsin (a serine protease) which is responsible for shifting the pH dependence of the channel activation and inactivation to more acidic pH1.These channels are expressed in the brain and in the nervous system2 but have also been found in the retina, testes, and other tissues3,4 where they are involved in many physiological processes including nociception5, learning and memory6, mechanosensation7 among others.
Research relevance and current trends
- Linking transporter/channel abundance to ionic homeostasis and excitability-related phenotypes.
- Studying compartment-specific localization (surface vs intracellular pools) and trafficking dynamics.
- Combining antibody readouts with functional assays for more complete interpretation.
Common research applications
- Western blot (WB): compare target abundance/size across lysates and conditions; consider isoforms/PTMs.
- Immunohistochemistry (IHC): examine spatial distribution in tissue and relate signal to cell-type composition.
- Immunofluorescence/ICC: assess subcellular localization and co-localization with markers in cells or sections.
- Flow cytometry (direct/indirect): quantify target-positive populations and shifts in expression across subsets.
- Live cell imaging (LCI): support extracellular-epitope detection on non-permeabilized cells when appropriate.
Interpretation typically benefits from comparing matched sample sets (e.g., treated vs control, WT vs KO/KD) and using orthogonal readouts where feasible.
Notes for experimental interpretation
- Isoforms and post-translational modifications can shift apparent molecular weight or epitope accessibility across samples.
- Cross-species signal may depend on epitope conservation; consult the provided homology note when selecting models.
- Permeabilization, fixation, and antigen retrieval can change accessibility of intracellular vs extracellular epitopes.
- Conceptual control: antigen preadsorption (blocking peptide) can help assess signal dependence on the immunogen region.
- Provided control suggestions: Negative control: BLP-SC031.
- Application notes: see product-specific dilution/usage notes and control concepts provided in the dataset.
